Taking medication is a common occurrence for many people, whether it is to soothe an aching head, regulate blood sugars, or to treat life threatening conditions, such as HIV or cancer. In the UK alone, over 900 million prescriptions are dispensed every year. Overseeing all of this are pharmacists: experts in medicines and their use. The Integrated Foundations of Pharmacy series supports those who are at the beginning of their journey to become a pharmacist. The reader will begin to understand how a drug molecule is made; the process that turns it into a medicine; the role the pharmacist has when dispensing that medicine; and what happens in the body when it is taken. Most importantly, the series shows how each of these aspects are integrated, reflecting the most up-to-date teaching practices. Pharmaceutics: the science of medicine design explores the different forms that medicines can take, and demonstrates how being able to select the best form - be it a tablet, injectable liquid, or an inhaled gas - requires an understanding of how chemicals behave in different physical states. Online Resource Centre The Online Resource Centre to accompany Pharmaceutics: the science of medicine design features: For registered adopters of the book: - Figures from the book, available to download. For students: - Self-assessment questions to help the reader to check and reinforce understanding of the material introduced in each chapter.

Properties and Formulation: From Theory to Real-World Application Scientists have attributed more than 40 percent of the failures in new drug development to poor biopharmaceutical properties, particularly water insolubility. Issues surrounding water insolubility can postpone or completely derail important new drug development. Even the much-needed reformulation of currently marketed products can be significantly affected by these challenges. More recently it was reported that the percentage increased to 90% for the candidates of new chemical entities in the discovery stage and 75% for compounds under development. In the most comprehensive resource on the topic, this third edition of Water-Insoluble Drug Formulation brings together a distinguished team of experts to provide the scientific background and step-by-step guidance needed to deal with solubility issues in drug development. Twenty-three chapters systematically describe the detailed discussion on solubility theories, solubility prediction models, the aspects of preformulation, biopharmaceutics, pharmacokinetics, regulatory, and discovery support of water-insoluble drugs to various techniques used in developing delivery systems for water-insoluble drugs. This book includes more than 15 water-insoluble drug delivery systems or technologies, illustrated with case studies and featuring oral and parenteral applications. Highlighting the most current information and data available, this seminal volume reflects the significant progress that has been made in nearly all aspects of this field. The aim of this book is to provide a handy reference for pharmaceutical scientists in the handling of formulation issues related to water-insoluble drugs. In addition, this book may be useful to pharmacy and chemistry undergraduate students and pharmaceutical and biopharmaceutical graduate students to enhance their knowledge in the techniques of drug solubilization and dissolution enhancement.
Colloid and Interface Science in Pharmaceutical Research and Development describes the role of colloid and surface chemistry in the pharmaceutical sciences. It gives a detailed account of colloid theory, and explains physicochemical properties of the colloidal-pharmaceutical systems, and the methods for their measurement. The book starts with fundamentals in Part I, covering fundamental aspects of colloid and interface sciences as applied to pharmaceutical sciences and thus should be suitable for teaching. Parts II and III treat applications and measurements, and they explains the application of these properties and their influence and use for the development of new drugs. Provides a clear description of the fundamentals of colloid and interface science relevant to drug research and development Explains the physicochemical/colloidal basis of pharmaceutical science Lists modern experimental characterization techniques, provides analytical equations and explanations on analyzing the experimental data Describes the most advanced techniques, AFM (Atomic Force Microscopy), SFA (Surface Force Apparatus) in detail

This book draws together contributions from basic, pharmaceutical and clinical sciences aimed at a better understanding of the structure and function of hERG and the molecular basis for compound binding. It features regulatory authority perspectives on preferred preclinical test systems and includes topics on hERG channel gating, regulation of functional expression, pharmacological properties of hERG/IKr channels, drug-induced long QT syndrome and preclinical evaluation and regulatory recommendations for assessing QT prolongation risks. Better understanding of the role of the hERG channel in drug-induced cardiac arrhythmias should ultimately lead to the development of important, new and safer medicines.
Drug Design, Volume IX examines various aspects of drug design and covers topics ranging from the consequences of the Hansch paradigm for the pharmaceutical industry to the Masca model of pharmacochemistry. A physicochemical basis for the design of orally active prodrugs is also considered, along with the use of interactive graphics in medicinal chemistry. Comprised of seven chapters, this volume begins with a discussion on efforts to avoid toxicity, not only of drugs, pesticides, and food additives but also of chemicals in general. The reader is then introduced to various aspects of the development of bioactive agents, including the optimization of existing agents by the design of more efficient prodrugs. Other chapters focus on Hansch's paradigm and its application to industrial practice; the application of multivariate statistics to pharmacochemistry; a logico-structural approach to computer-assisted drug design; and spatial arrangements in bioactive molecules. This book will be of interest to pharmacologists, chemists, and those involved in drug design.

The Quality Control of Medicines documents the proceedings of the 35th International Congress of Pharmaceutical Sciences, organized by the Pharmaceutical Society of Ireland on behalf of the Federation Internationale Pharmaceutique, held in Dublin, on 1-5 September 1975. The theme chosen for the Congress was ""the basis for the quality control of medicines"", because of the importance and relevance of quality control in the production and distribution of medicines at national and international levels. This volume is arranged according to the manner in which the theme of the Congress was developed by the eminent invited speakers. Following the inaugural address a main symposium was held where five speakers presented a review of the quality control of medicines under the general headings of (i) chemical and physical aspects; (ii) biological aspects; (iii) control of drug delivery systems; (iv) storage problems; and (v) problems of international control. Certain aspects of the content of the main symposium were then developed in greater depth in parallel symposia. In the first parallel symposium some novel physicochemical aspects of the quality control of medicines were treated under the headings of spectrofluorimetry, mass spectrometry, detection in gas chromatography, and automation in pharmaceutical analysis. The second parallel symposium developed certain microbiological aspects of quality control under the headings of sterility testing and microbiological control of non-sterile products and ophthalmic preparations. The final symposium on submissions to regulatory bodies and international aspects of drug control covered aspects of politics in submissions, regulatory problems in small countries, and various pharmacopoeial problems.
